用 C# 实现一个简单的 Restful Service 供外部调用，大体总结为4点：
- The service contract (the methods it offers).
- How do you know which one to access from the URL given (URL Routing).
- The implementation of the service.
- How you will host the service.
详细的基本步骤如下所示：
1）：工程结构（Class Library Project）
2）： IRestDemoService.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Web; namespace EricSunRestService
{
[ServiceContract(Name = "RestDemoServices")]
public interface IRestDemoServices
{
[OperationContract]
[WebGet(UriTemplate = Routing.GetClientRoute, BodyStyle = WebMessageBodyStyle.Bare)]
string GetClientNameById(string Id);
} public static class Routing
{
public const string GetClientRoute = "/Client/{id}";
}
}
3）：RestDemoService.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.ServiceModel.Activation; namespace EricSunRestService
{
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Single, IncludeExceptionDetailInFaults = true)]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class RestDemoServices : IRestDemoServices
{
public string GetClientNameById(string Id)
{
string ReturnString = "HaHa id is: " + Id; return ReturnString;
}
}
}
4）：Host Service 工程结构 （Console Application）
5）：Program.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using EricSunRestService;
using System.ServiceModel.Web; namespace EricSunHostService
{
class Program
{
static void Main(string[] args)
{
RestDemoServices demoServices = new RestDemoServices();
WebServiceHost _serviceHost = new WebServiceHost(demoServices, new Uri("http://localhost:8000/DemoService"));
_serviceHost.Open();
Console.ReadKey();
_serviceHost.Close();
}
}
}
6）：运行Host程序，在浏览器中输入对应Service的Url
